Don't let your frontend system design fail! Learn how to define and tackle Non-Functional Requirements (NFRs) to build scalable, high-performance web applications. What is in this video? In many system design interviews, candidates jump straight into technical stacks. In this video, we explain why starting with NFRs is the key to a successful design. We break down the "ilities" of frontend—performance, accessibility, and maintainability—and show you how to present them to your interviewer. 💡 Key Topics Covered: Defining NFRs in Frontend: Why it's about "how" the system works, not just the features [00:20]. Performance & Core Web Vitals: Discussing LCP, FID, and CLS as critical design constraints. Accessibility (a11y): Why making a system inclusive is a core non-functional requirement. Security & Data Privacy: Handling XSS, CSRF, and secure storage on the client side. Scalability & Maintainability: Designing for large teams and growing codebases (Micro-frontends, Component Libraries). SEO & SSR vs. CSR: How your architectural choices impact discoverability. 📌 The NFR Checklist: Performance: Load times, time-to-interactive, and bundle optimization. Availability: Offline support (PWA) and graceful degradation. Reliability: Error logging and monitoring (Sentry, LogRocket). Portability: Cross-browser support and responsive design across devices. Target Audience: Senior Frontend Developers Software Architects Engineering Managers & Candidates preparing for L5/L6 interviews at companies like Google, Amazon, or Meta.
